Buy One Entree Get One free Cupons

Idk when this started, or where exactly they are available at, but i have seen many quest in the park with BOGO Entree coupons that are usable at ABC Commissary, Backlot Express, and Studio Catering Company. My guess is to push the new menus at the Counter Service, to spread the word that studios CS is getting better. Anyone received one of these coupons or know anything about them?

I didn't get it when I came into DHS on Sunday morning but if it's true, it's a good deal. It also shows you how much markup there is on food if they can give away 50% of the entrees and still make money
